 (1) Description
 The ground air conditioning/air starting door is made of honeycomb
 core. The honeycomb core is bonded between several layers of foil.
 The door is attached with the door hinge to the belly fairing. The door hinge is riveted to the door and screwed to the belly fairing. Two latch assemblies are riveted to the door to lock the door. The locking pins of the latch assemblies engage with the hooks and the door is then flush with the belly fairing. The hooks are screwed to the catch brackets which are attached at the belly fairing. A spring rod assy is installed between the push rod door fitting and the push rod fitting. The spring rod assy consists of a spring and a shaft which pivots between these fittings. It forms an overcenter device which retains the door in the fully open position and assists when the door closes.
